Kiosk keys

This article contains a listing of known keys that can be used with Kiosk and what they do. How to actually use these keys and other capabilities of Kiosk such as URL restrictions, creating assigning profiles, etc. is covered in the Introduction to Kiosk article.

Which configuration file to put these entries in depends on whether you wish to make them global to all applications or specific to one application. To make the restrictions valid for all applications, put them in kdeglobals. To enable a restriction for a specific applications place them in the application-specific configuration, e.g. konquerorrc for Konqueror.

Application Action Restrictions

These keys disable actions that are commonly found in KDE applications. To use these actions, create a section in kdeglobals that looks like this:

action/kwin_rmbContext menus on window titlebar and frame


Locking down the entire config with [$i] will cause everything to be immutable. Locking a Containment group will render that one group of widgets to be immutable, and locking a widget itself will cause it to not be movable as well as otherwise locked. In addition, the following resource restrictions are available:
plasma/allow_configure_when_locked (since Plasma 4.4)Whether widgets and containments can be configured when immutable / locked. The default is true as a convenience to users.
plasma/containment_actions (since KDE Frameworks 5.49)Whether or not to allow Plasma mouse actions on desktop and panels (most notably context menus, but also mouse wheel to switch virtual desktops, etc.)
plasma/plasmashell/unlockedDesktop (since Plasma 5.0)

Whether to allow widgets in Plasma to be unlocked; when false, the following restrictions apply:

  • Widgets cannot be unlocked
  • Favorites and applications in the application launchers cannot be added, removed, rearranged, or otherwise altered (since Plasma 5.7)
  • Application launchers in the task manager cannot be added or removed (since Plasma 5.8)
plasma-desktop/scripting_console (since Plasma 4.4)Whether the plasma desktop scripting console is accessible or not.
plasma-desktop/add_activities (>= 4.7.1)Whether the user may add new activities or not.


Plasma offers to download new widgets, wallpapers, scripts, and other 3rd party add-ons from the KDE Store using the KNewStuff (aka "Get Hot New Stuff") framework. The buttons are typically labeled "Get New ..." with a "star" icon. If this feature is undesirable it can be disabled using the following key:
ghns (since KDE Frameworks 5.27)Whether the Download Dialog of Get Hot New Stuff can be accessed


Application .desktop files can have an additional field X-KDE-AuthorizeAction.

If this field is present the .desktop file is only considered valid if the action(s) mentioned in this field has been authorized. If multiple actions are listed they should be separated by commas (',').

If the .desktop file of an application lists one or more actions this way and the user has no authorization for even one of these actions then the application will not appear in the KDE menu, will not allow execution via that .desktop file and will not be used by KDE for opening files of associated mimetypes.

File Dialog

These keys disable actions that are found in the KDE file dialog. To use them, create a section in kdeglobals that looks like this:

[KDE Action Restrictions][$i]
action/homeGo to home directory
action/upGo to parent directory
action/backGo to previous directory
action/forwardGo to next directory
action/reloadReload directory
action/mkdirCreate new directory
action/toggleSpeedbarShow/hide sidebar
action/sorting menuSorting options
action/short viewSelect short view
action/detailed viewSelect detailed view
action/show hiddenShow/hide hidden files
action/previewShow/hide preview
action/separate dirsShow/hide separate directories


There are several keys that restrict various aspects of the KDE print dialog and printing system. To use them, create a configuration section like this:

[KDE Resource Restrictions][$i]
print/<resource key>=false

Note how each of the printing keys start with print in the configuration file.

print/copiesDisables the panel that allows users to make more than one copy.
print/dialogDisables the complete print dialog. Selecting the print option will immediately print the selected document using default settings. Make sure that a system-wide default printer has been selected. No application-specific settings are honored when this restriction is activated.
print/optionsDisables the button to select additional print options.
print/propertiesDisables the button to change printer properties or to add a new printer.
print/selectionDisables the options that allows selecting a (pseudo) printer or change any of the printer properties. Make sure that a proper default printer has been selected before disabling this option. Disabling this option also disables print/system, print/options and print/properties.
print/systemDisables the option to select the printing system backend, e.g. CUPS. It is recommended to disable this option once the correct printing system has been configured.

Resource Restrictions

KDE applications can take advantage of many types of resources such as configuration data, caches, plugin registries, etc. These are loaded from both system-wide as well as from per-user locations on disk. It is possible to restrict the use of the per-user resources directories, preventing users from adding to or altering existing shared resources.

This is accomplished by creating a section like this in a configuration file:

[KDE Resource Restrictions][$i]
<resource key>=false

The following resources can be used as keys and controlled in this manner:

alln/aAll resources listed in this table
autostartshare/autostartApps to start on login
datashare/appApplication data
data_<appname>share/appsApplication data for the application named
htmlshare/doc/HTMLHTML files
configshare/configApplication configurations
xdgdata-appsshare/applicationApplication .desktop files
soundshare/soundSound files
localeshare/localeLocalization data
servicesshare/servicesProtocols, plugins, kparts, control panels, etc. registry
servicetypesshare/servicestypesPlugin definitions, referenced in services registry entries
mimeshare/mimelnkMimetype definitions
wallpapershare/wallpapersDesktop wallpaper images
templatesshare/templatesDocument templates
exebinExecutable files


In kdeglobals in the [KDE Action Restrictions] group:
opengl_screensaversDefines whether OpenGL screensavers are allowed to be used.
manipulatescreen_screensaversDefines whether screensavers that manipulate an image of the screen (e.g. moving chunks of the screen around) are allowed to be used.

Automatic logout

In kscreensaverrc:


The timeout is the time in seconds that the user must be idle for before the logout process is automatically started. Be careful with this capability as it can lead to data loss if the user has unsaved files open.

Session Capability Restrictions

These keys apply to various capabilities associated with a desktop session and are not application specific. To use them, create a section in kdeglobals that looks like this:

[KDE Action Restrictions][$i]
custom_configWhether the --config command line option should be honored. The --config command line option can be used to circumvent locked-down configuration files.
editable_desktop_iconsDefines whether icons on the desktop can be moved around. In order to prevent adding, removing, or renaming icons, you should set the desktop folder read-only. *(since Plasma 5.14)
lineedit_text_completionDefines whether input lines should have the potential to remember any previously entered data and make suggestions based on this when typing. When a single account is shared by multiple people you may wish to disable this out of privacy concerns.
lineedit_reveal_passwordDefines whether password input fields may have a button that allows showing the password in plain text. *(since KDE Frameworks 5.30 and/or Plasma 5.9)
action/lock_screenDefines whether the user will be able to lock the screen.
logoutDefines whether the user will be able to logout from the Plasma session.
movable_toolbarsDefines whether toolbars may be moved around by the user. See also action/options_show_toolbar.
run_commandDefines whether the "Run Command" (Alt-F2) option is available. Note: To also disable desktop context menu run command action/run_command is required at [KDE Action Restrictions]

Defines whether users may execute desktop files that are not part of the default desktop, KDE menu, registered services and autostarting services.

  • The default desktop includes the files under .local/share/kdesktop/Desktop but not the files under $HOME/Desktop.
  • The KDE menu includes all files under $KDEDIR/share/applnk and $XDGDIR/applications
  • Registered services includes all files under $KDEDIR/share/services
  • Autostarting services include all files under $KDEDIR/share/autostart but not the files under $KDEHOME/Autostart

Whether a shell suitable for entering random commands may be started. This also determines whether the "Run Command" option (Alt-F2) can be used to run shell-commands and arbitrary executables. Likewise, executables placed in the user's Autostart folder will no longer be executed. Applications can still be autostarted by placing .desktop files in the .local/share/autostart directory. See also run_desktop_files.

You probably also want to activate the following resource restrictions:

  • "appdata_kdesktop" - To restrict the default desktop.
  • "apps" - To restrict the KDE menu.
  • "xdgdata-apps" - To restrict the KDE menu.
  • "services" - To restrict registered services.
  • "autostart" - To restrict autostarting services.

Otherwise users can still execute .desktop files by placing them in e.g. .local/share/kdesktop/Desktop

skip_drmDefines if the user may omit DRM checking. At the time of writing, this primarily applies to document formats with a DRM mechanism (e.g. PDF).
action/start_new_sessionDefines whether the user may start a new session.
action/switch_userDefines whether user switching is allowed.


Whilst telemetry is disabled by default, a user can choose to enable it inside applications.
